摘要:
A method of operating a multi-axis fiber scanner having a base including a base plane includes providing a source of electromagnetic radiation, directing the electromagnetic radiation through a fiber link that passes through the base plane of the base along a longitudinal axis orthogonal to the base plane, and supporting a retention collar positioned a distance from the base plane. The method also includes actuating a first piezoelectric actuator among a plurality of piezoelectric actuators to decrease the distance between a first side of the base and the retention collar, actuating a second piezoelectric actuator among the plurality of piezoelectric actuators to increase the distance between a second side of the base and the retention collar, and scanning the fiber link in a scanning plane.
